Financial planning is full of apparent contradictions. Sometimes the things that seem sensible are harmful, and sometimes the things that seem counterintuitive are exactly what help people succeed.
When it comes to money, most people assume that success comes from doing the obvious things.
Spend less, save more, check your investments regularly, make every decision based on the numbers. Simple!
Except that many of the most effective financial behaviours are actually quite counterintuitive. In fact, some of the things that seem like they should help can end up making things worse, while some things that appear irrational can improve both financial outcomes and quality of life.
Here are three money truths that don’t always make sense at first glance but are surprisingly important.
1. Sometimes being impulsive helps you stay disciplined
Most financial advice focuses on avoiding impulse spending altogether.
While that sounds sensible, it often creates an “all or nothing” mindset. Every purchase becomes something to analyse, justify, and potentially feel guilty about. Over time, constantly saying no to yourself can become exhausting.
The reality is that long-term financial success doesn’t require perfection. It requires consistency.
For many people, allowing themselves occasional spontaneous spending can make it easier to stick with a sensible financial plan. In fact, building room for these small pleasures into your spending can prevent the feeling of deprivation that often causes people to abandon good habits entirely.
Think of it like a healthy diet. The person who allows themselves the occasional treat often sticks with it longer than the person trying to be perfect every day.
Financial discipline isn’t about never spending money impulsively. It’s about making sure those moments don’t become the norm.
2. Doing less with your investments can produce better results
When markets become volatile, our instincts tell us to act. We want to check our portfolios more frequently, react to news headlines, and make changes in response to what’s happening around us. It feels productive, it feels responsible.
Yet investors who constantly monitor and adjust their portfolios often achieve worse outcomes than those who leave well-constructed plans alone.
One reason is that frequent monitoring exposes us to short-term market noise. The more often you look, the more likely you are to see losses, and the more tempted you become to make emotional decisions.
Research from Portfolio Thinking illustrates this perfectly. If you check your portfolio daily, there’s roughly a 49% chance you’ll see a negative return. Check annually and that falls to around 29%. Stretch your time horizon to ten years and the probability drops to only around 4%.
The irony is that the more attention we pay to short-term movements, the harder it becomes to stay focused on long-term goals. Successful investing is often less about finding the perfect investment and more about avoiding unnecessary interference. After all, making a decision not to change something is still an active decision.
3. The best financial decision isn’t always the best life decision
Financial planning involves numbers, but life doesn’t.
Many decisions can be justified mathematically. Working a few more years before retirement may improve your financial position. Taking less holiday could increase your savings. Downsizing your home might improve your balance sheet.
But financial planning isn’t about maximising spreadsheets. It’s about helping people live the lives they want. The statistically optimal decision isn’t always the right decision.
A client might choose to retire slightly earlier despite having a little less money than they could have accumulated. Another may decide to spend more travelling while they’re healthy enough to enjoy it. Someone else might choose to help their children financially even though keeping the money invested would produce a better long-term return.
Viewed purely through a financial lens, these decisions may not be optimal. Viewed through a human lens, they may be exactly right.
Money is a tool, not the objective. The purpose of good financial planning is not to maximise wealth at all costs. It’s to help align financial decisions with what matters most to you.
Final thoughts
One of the reasons personal finance is so challenging is that human behaviour doesn’t always follow simple logic.
Sometimes allowing yourself a little spontaneity helps you remain disciplined. Sometimes doing less leads to better investment outcomes. Sometimes the best decision on paper isn’t the best decision in practice.
The most successful financial plans are rarely the most complicated. They are the ones that recognise that money is ultimately there to support a life well lived.
That doesn’t always make sense … until it does!
